Hi.
When you have a TelerikGrid, with on OnRead event making an async call, the pager that comes with TelerikGrid doesn't show the mobile view when on a narrower device.
I created a blazor repl here: https://blazorrepl.telerik.com/mxOPbEuZ29PQRAQk02
If you view the repl in browser, open dev tools and toggle the device toolbar, and set your viewport width to something around 320px. If it loads into the preview right away, after having been first rendered on normal screensize, then the pager will adapt. To see the bug, go to the code tab, then the preview tab to have it do its initial render on mobile width. You will see something like this:
This is an issue live currently on my own websites, which had been reported to me by customers. I believe this only occurs when using the Grid's OnRead, and making an asynchronous call within it (which I represented in the repl with a Task.Delay)
I'm using as early as 3.5.0 in production, but can repro this on latest, 3.7.0.
We still have some problems with printed pdf quality after the updates in 6.0.0. When pdf is printed using Telerik PDF viewer it seems it gets processed/rasterized and loses quality.
Hello,
i am trying to add a Clear Button inside the DropDownList-Component.
I tried to follow the instructions provided here: How do I add a Clear button to a DropDownList? in UI for Blazor | Telerik Forums respectiveley here: Telerik REPL for Blazor - The best place to play, experiment, share & learn using Blazor.
But unfortunateley, the button is never inside the component. It's always next to it or under the component.
In your example provided above, the button is inside the component.
I would love to have any solution for this one. A clear button is needed quite often.
I also have attached our custom component, where we use the Telerik DropDownList Component.
Thank you
Hello together,
we are running into a problem with TelerikPdfViewer. When clicking the download button, download starts and performs properly.
BUT: the downloaded PDF file does not match the PDF that was provided via Data="@PdfData". On download something internally prepends some text to the PDF:
–€À³JS.ReceiveByteArray’Æ ‘¢%PDF-1.7 %úûüý 3 0 obj <</ca 1.00000 /AIS false >> endobj 5 0 obj
The original PDF file starts at "%PDF-1.7" (end of first line). That part before (including that "JS.ReceiveByteArray") was somehow added during the download workflow by Telerik. We ensured that the PDF data we provided to the viewer (via Data="@PdfData") ist valid. We did so by inspecting the byte[]-Array manually in the debugger as well as downloading it via a JS function to the client.
This is how we are using the TelerikPdfViewer. But the error occurs no matter if we are handling the OnDownload-Event (setting the filename) or not handlign that event at all (i.e. eliminating the OnDownload="@OnPdfDownload" completely)
<TelerikPdfViewer Data="@PdfData" Width="100%" Height="100%" Zoom="1m" OnDownload="@OnPdfDownload">
<PdfViewerToolBar>
<PdfViewerToolBarPagerTool />
<PdfViewerToolBarSpacer />
<PdfViewerToolBarZoomTool />
<PdfViewerToolBarSelectionTool />
<PdfViewerToolBarSearchTool />
<PdfViewerToolBarSpacer />
<PdfViewerToolBarDownloadTool />
<PdfViewerToolBarPrintTool />
</PdfViewerToolBar>
</TelerikPdfViewer>
We use Telerik.UI.for.Blazor (6.2.0).
Thanks for your feedback on this issue and best regards!

We need a formal, Accordion component. This is missing like a sore thumb !
The Accordion should be the first component in the component list.
Using the panel bar is not the same as the functionality of Accordion. So, do not mark this request as a duplicate of a panel bar enhancement request.
This is a simple component and I request you to prioritize and release it urgently in the next release.
Thanks.
Bug reproduced systematically on web browser Edge (131.0.29.03.146) & Firefox (134.0).
Beware: culture is fr-FR
Scheduler component sometimes put appointments at wrong coordinates (hour if ok but the day is wrong).
The screenshot "ExampleWrongCoordinates.png" set an example of an item wrongfully located. In this picture, console log shows details of the razor element who's supposed to be located on Tuesday 14th of January 2025 .. but which is rendered on Monday instead!
Appointments model defines "default (expected) property names Start & End":
private DateTime _start;
public DateTime Start
{
get { return _start; }
set { _start = value; }
}
private DateTime _end;
public DateTime End
{
get { return _end; }
set { _end = value; }
}
View is MultiDay but the glitch is the same on Week view.
Now if we switch on day view and navigate to Tuesday 14, scheduler shows the appointment on hours column! If we click it, a JS error is raised (Cf screenshot "ClickAppointmentWrongCoordinates.png").
We have recently update to version 7.0.0 of Telerik for Blazor controls.
We have also access to Progress ThemeBuilder application which we use to customize the default Material theme.
After the update to version 7 and also upgrading and compiling the new theme file for our application, TabStrip items fail to display the correct css and defaults to the theme's original css.
ThemeBuilder produces rules for the tab item items with the following path
.lvs-tabstrip.k-tabstrip .k-tabstrip-items-wrapper .k-tabstrip-items.k-reset.k-tabstrip-items-start .k-item.k-tabstrip-item
where the actual control generates the following
.lvs-tabstrip.k-tabstrip .k-tabstrip-items-wrapper .k-tabstrip-items.k-reset.k-tabstrip-items-start .k-item
As you can see it is missing the k-tabstrip-item class and the custom theme fails to render correctly. Either Telerik blazor libary did not add this extra class to each tab item or theme builder is inserting this class when it should not.
I can place this extra class on each TabStripTab element on its Class property, but I feel this is something that the actual Telerik for Blazor libray should do.
Looking at the source code of Telerik for Blazor library, the TabStipTab component generates add the k-item as default and then applies the value of property ClassToRender and its value is
$"{ActiveCssClass} {DisabledCssClass} {Class} {FirstItemClass} {LastItemClass}".Trim()
The Class is an empty string, which I currently use to "fix" the problem but I certainly would like a better solution like a real fix :)
Thank you telerik team

On a grid grouped by a field (using GroupDescriptors) where the amount of records exceed the page limit, therefore generating multiple pages, provide an option to keep the collapsed/expanded states of the groups when navigating through the pages.
In-house we implemented the following approach to mitigate this issue: when calling OnRead event, after processing the data (order, filter, group, etc) we're mapping the groups and subgroups to its corresponding indexes. When page changing, we then store the current state of the groups, alongside its keys (aka the label of the group). After page changing and mapping the groups and subgroups again, we just match the group names stored in this temporary state with the group names of the new page and restore the state.
For example: start with all groups initially collapsed, page 1 has groupA and groupB and user expanded groupB, changed to page 2, which has the remaining records of groupB and groupC. In this case it will restore groupB as expanded while groupC keeps collapsed.
Example to demonstrate the issue: https://blazorrepl.telerik.com/melmEeFi43owNZBe50
On a grid grouped by one or more fields, provide an option for end users to expand/collapse all rows at will. The following image is a suggestion of where this option (most likely a button) should appear:
When I am dynamically adding or removing tabs I am hitting a variety of problems targeting:
The active tab is not correctly set
the focus is not always set to the active tab
upon adding/removing a tab all tabs are re-created and their content is not persisted
This is causing some data loss, picklist filter loss, lag time when opening and closing tabs
When SelectOnFocus="true"
is enabled on the NumericTextBox control, and a format (e.g., Format="N1"
) is set, the SelectOnFocus
functionality does not select all text if the decimal value has no trailing digits. For instance, with the value 76
, the text is not selected on focus, but with the value 76.1
, the text is selected correctly.
<TelerikNumericTextBox @bind-Value="@DecimalValue" Format="N1" SelectOnFocus="true"/>
@code {
private decimal DecimalValue = 76;
}
Steps to Reproduce:
SelectOnFocus="true"
.Format="N1"
.76
(with no trailing digits after the decimal point).Expected Behavior:
The entire text (in this case, 76.0
) should be selected when the NumericTextBox gains focus.
Actual Behavior:
The text is not selected when the NumericTextBox gains focus if the value has no trailing digits after the decimal point (e.g., 76
). However, if the value includes trailing digits (e.g., 76.1
), the text is selected as expected.
Hi Team,
I am looking for captcha component to verify user as human like below screenshot. Please let me know if this feature is available
Would be nice to have an Expansion Panel like this one:
